In the paper the results obtained from experiments at a modelled reinforced building in case of a direct lightning strike are compared with calculations. The comparison includes peak values of the magnetic field Hmax, its derivative (dH/dt)max and of induced voltages umax in typical cable routings. The experiments are performed at a 1:6 scaled building and the results are extrapolated using the...

We describe a novel framework for the joint processing of color and shape information in natural images. A hierarchical non-linear spatio-chromatic operator yields spatial and chromatic opponent channels, which mimics processing in the primate visual cortex. We extend two popular object recognition systems (i.e., the Hmax hierarchical model of visual processing and a sift-based bag-of-words app...

سابقه و هدف: ورود گونه­­ های ماهی مهاجم دراکوسیستم ­های آبی، سبب بروز انواع اثرات منفی اکولوژیکی اقتصادی-اجتماعی می ­­شود. اولین گام در تجزیه تحلیل مخاطرات ناشی از گونه­ غیر­بومی، شناسایی خطر است بر این اساس ابزارهای متعددی برای ارزیابی خطرات تهاجمی غیربومی به منظور پشتیبانی تصمیم گیرندگان گونه ­­ها ایجاد شده است. هدف پژوهش قدرت تیلاپیای شکم قرمز (Coptodon zillii) حوضه آبریز تالاب شادگان (حوضه‌...

Oxygen binds to hemoglobin cooperatively, and a correct description of this binding is relevant not only for understanding the mechanisms involved molecular processes but also clinical purposes. Hill’s equation, derived over hundred years ago, still simplest most efficient way perform description. However, in terms accuracy, it inferior Adair´s which contains more parameters. We proposed use mo...

در آشکار‌ساز CMS نسبت‌های انشعاب بوزون هیگز مدل استاندارد به جفت‌‌های J/ψ(1S) و cc ترتیب برابر 2-10×1/8 2-10×2/89 اندازه‌گیری شده است. لحاظ نظری یکی از سناریوهای ممکن برای تولید مستقیم این است که آغاز جفت واپاشی نماید سپس مرحله‌ی بعد هر یک کوارک‌های c طور مزون ترکش کنند. بر اساس سناریو مقاله بطریق کوارک‎های با استفاده نظریه اختلال مکانیک کوانتومی رنگ (pQCD) نظر گرفتن حالت‌های قطبش طولی عرضی محا...

The retention-releasing patterns of the double-grid grating sieve placed on deck purse seiners were revealed for four case species (Sardina pilchardus, Sardinella aurita, Engraulis encrasicolus and Boops boops) using a simulated data predicted from total length (TL) – maximum height (Hmax) TL width (Wmax) regressions. To calculate these relationships, samples collected during commercial seine o...

Understanding how functional traits and diversity modulate plant interactions within forests is becoming a widespread research goal in ecology. We applied neighbourhood analysis to Mediterranean biodiversity manipulation experiment (IDENT-Macomer) assess the importance of predicting tree diameter increments (DI) mixed forest. used weigh competition index (NCI) dispersion (FDis), which metric. f...

Abstract Information about the absolute stress state in upper crust plays a crucial role planning and execution of, e.g., directional drilling, stimulation exploitation of geothermal hydrocarbon reservoirs. Since many these applications are related to sediments, we present refined geomechanical–numerical model for Germany with focus on sedimentary basins, able predict complete 3D tensor. The la...
